Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
69 words
A bag construction comprising a pair of bag units, means for separably interconnecting the peripheral mouth portion of one bag unit to the peripheral mouth portion of the other bag unit to provide for communication between the interior portions of said bag units, said interconnecting means including means for closing the mouth portion of one bag unit and means for closing the mouth portion of the other bag unit.
Claim 2
Dependent Claim
69 words
A bag construction comprising a pair of bag units, means for separably interconnecting the peripheral mouth portion of one bag unit to the peripheral mouth portion of the other bag unit to provide for communication between the interior portions of said bag units, said interconnecting means including means for closing the mouth portion of one bag unit and means for closing the mouth portion of the other bag unit.
Claim 3
Dependent Claim
38 words
A bag construction as in claim 1, wherein said interconnecting means comprises slide fastener elements mounted on the peripheral mouth portion of each of said bag units and slide fastener closure means for engagement with said fastener elements.
Claim 4
Dependent Claim
81 words
A bag construction as in claim 2, wherein tape means carrying said fastener elements is mounted on opposed peripheral mouth portions of one bag unit and tape means carrying said fastener elements is mounted on opposed peripheral portions of the other bag unit, said slide fastener closure means comprising one slide fastener closure member interconnecting slide fastener elements on both of said tape means and a second slide fastener closure member interconnecting slide fastener elements on both of said tape means.
Claim 5
Dependent Claim
99 words
A bag construction as in claim 1 wherein said interconnecting means comprises laterally related openings along the mouth edge portion of each bag unit, said bag units being arranged with their mouth edge portions in telescoped relation and the openings on one bag unit being in registry with the openings on the other bag unit, and lacing means threadable through said registering openings for interconnecting the peripheral mouth portions of said bag units, said lacing means being removable to separate said bag units and then threadable through openings in one of said bag units to form a closure therefor.
Claim 6
Dependent Claim
33 words
A bag construction as in claim 4 wherein each bag unit has outermost transverse edge portions in separated relation, and means for separably connecting said outermost transverse edge portions of each bag unit.
Claim 7
Dependent Claim
101 words
A bag construction comprising a pair of bag units, each unit having side edges and at least one set of transversely extending opposed edge portions for gaining access to the interior thereof, means for separably interconnecting the transverse edge portions of one bag unit to the transverse edge portions of the other bag unit about the periphery of said edge portions to provide for communication between the interiors of said bag units, and means for closing at least one set of transverse edge portions of each bag unit to provide a closed bottom edge for each of said separated bag units.
Claim 8
Dependent Claim
101 words
A bag construction comprising a pair of bag units, each unit having side edges and at least one set of transversely extending opposed edge portions for gaining access to the interior thereof, means for separably interconnecting the transverse edge portions of one bag unit to the transverse edge portions of the other bag unit about the periphery of said edge portions to provide for communication between the interiors of said bag units, and means for closing at least one set of transverse edge portions of each bag unit to provide a closed bottom edge for each of said separated bag units.
Claim 9
Dependent Claim
137 words
A bag construction as in claim 6 wherein one bag unit has one set of opposed transverse edge portions, and thE other bag unit has two sets of opposed transverse edge portions at the opposite ends thereof respectively, said interconnecting means connecting the one set of opposed transverse edge portions of said one bag unit with one of the two sets of respectively opposed transverse edge portions of the other bag unit; said other bag unit including a movable flap member for disposition with the peripheral edge thereof adjacent the opposed edge portions of said one of the two sets of transverse edge portions, and means on the peripheral edge of said flap member and the opposed edge portions of the one of the two sets of transverse edge portions for separable connection by said interconnecting means.
Claim 10
Dependent Claim
125 words
A bag construction as in claim 6, wherein said interconnecting means comprises a pair of slide fastener tapes secured to the transverse opposed edge portions of each bag unit, and a pair of slide fastener members for respectively interconnecting the slide fastener tapes of one bag unit with the corresponding and adjacent slide fastener tapes of the other bag unit, one of said pair of slide fastener members being operable upon separation of said bag units from each other, to interconnect the pair of slide fastener tapes of one bag unit to provide closure means therefor; the other of said pair of slide fastener members being operable to interconnect the pair of slide fastener tapes of the other bag unit to provide closure means therefor.
Claim 11
Dependent Claim
104 words
A bag construction as in claim 6, wherein said bag units are arranged with one set of transverse opposed edges of one bag unit in telescoped relation to one set of transverse opposed edges of the other bag unit, said bag units having a series of laterally spaced openings along the transverse edge portions of each bag unit, said interconnecting means comprising lacing means selectively threadable through successive sets of registering openings in the telescoped edge portions of said bags or threadable through opposed registering openings in the opposed transverse edge portions of each of the separated bag units to form closure means therefor.
